MainNav GPS watch

Though much larger than a conventional watch, the MW-705 by MainNav may be worthwhile for several reasons. It uses the new SiRFstar III LP receiver, and is able to track up to 12 satellites at once, saving power with an OLED display and an adjustable acquisition rate. Sports enthusiasts meanwhile can monitor their speed, heartrate and/or pedaling rhythm, and also check altitude and ambient temperature. Location is only displayed in terms of coordinates, but the built-in Bluetooth transmitter can send to a more elaborate device. It is not clear, unfortunately, whether the 705 will make it outside its home country of Taiwan. [viaNaviGadget]
